2 Ω के आंतरिक प्रतिरोध वाले 12 V DC स्रोत द्वारा किसी प्रतिरोधी लोड को प्रदान की जा सकने वाली अधिकतम शक्ति (maximum power) कितनी है?

Two resistors of 30 Ω and 60 Ω are connected in parallel. Determine the equivalent resistance between the terminals.

A practical current source has a short-circuit current Is = 4 μA and internal resistance Rs = 1.2 MΩ. The values of voltage Vs and internal resistance Rs for its equivalent Thevenin voltage source are:
